1. A one-piece suit worn by parachutists for jumping.
2. A garment fashioned after this, usually combining a shirt or bodice with shorts or trousers in one piece.

EX1:
- Jumper : Arg the wind is sneaking under my shirt and basically undressing me, I can't see anything and the wind hurts.
- Parachutists : You should have worn a jumpsuit.
- Jumper: It's okay I'm just committing suicide anyway.

EX2:
The second piece of fashion that you'll ever see if Jason Voorhees catches you, after seeing his bloody hockey mask. Unless a machete can be considered a fashion accessory (but you'll feel it more than see it), or if he's not wearing his jumpsuit that day.

EX3:
What Slipknot wears on stage to make you focus on the music instead of them and fashion.
